M ETALLIC POST.

SPECIFICATION forming part of Letters Patent No. 431,276, 1ated July 1, 1890.

Application filed March 29, 1890.

To all whom it may concern:

Be it known that I, FOSTER MILLIKEN, of New York city, in the county and State of New York, have invented a new and useful Improvement in Metallic Posts, of which the following is a'full, clear, and exact description.

My invention relates to an improvement in metallic posts especially adapted for use when the post or strut is subjected to a pull or strain at a point above the base; and the object of the invention is to provide a strong and durable post capable of being conveniently and expeditiously climbed when occasion may demand, which will be open for con-- venient inspection and ventilation, will be of a neat and ornamental design, and can be constructed from a minimum amount of material and with very little labor.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the post. Fig. 2 is a front elevation. Fig. 3 is a section on line a: m of Fig. 2, and Fig. 4 is a section on line y y of Fig. 2.

The post A is constructed of two or more segments 10, usually tour, which segments are preferably similar to those employed in the construction of the well-known Phoenix columns. The segments are provided at each side with a longitudinal flange 11, extending outwardly at a right angle to the body, as illustrated in Figs. 3 and 4.

In forming the post, if four segments are used, two are employed to constitute each side section thereof, and between the opposed side flanges of the two segments forming a side section thimbles 12 are horizontally introduced, being held in place by bolts or rivets 13, which bolts or rivets are passed through them and the flanges, as shown at a in Figs. 3 and 4, and between the opposite flanges of the opposed side sections washers 141 are in Serial No. 345,874. (No modal.)

serted, the said flanges and washers being brought to close contact by bolts or rivets 15, passed through them, as illustrated at a in the said Figs. 3 and 4. The thimbles at the base of the column are longer than at the top, and the Washers may be thinnest at the top, whereby a conical shape is imparted to the column, and the said thimbles and wash ers are placed one above the other a sufflcient distance apart to provide for an ample ventilation of the column and to constitute rungs, especially the thimbles, for the ascent and descent of a Workman or an inspector.

The thimbles and Washers may be con-= structed of any preferred material, and the inclination of the column with respect to its length may be gradual from its base to the top, or the inclination may be made to commence at any point in its length. Different lengths of thimbles will give difierent-shaped columns-as, for instance, round, oblong, elliptical, or any form of a closed curved line.

I11 special cases the openings between the segments which are diametrically opposite are entirely closed, or the flanges are separated only by washers of the same thickness, and the other flanges are spaced apart at the bottom and the space gradually decreased toward the top, Where the flanges may meet or be provided with intervening Washers only. Gussetplates 16 may be introduced at intervals to produce stiffness and keep the column in shape.

My invention is especially intended for use, as heretofore stated, when the post or strut is subjected to a pull or strain at a point above the base. The additional diameterat the base, due to spreading the segments, causes the post to Withstand the strain better, and it will not deflect as much as it would were the column of a diameter at its base equal only to that at the top. 1 t

The post as constructed can also be readily inspected and painted, and an yportion thereof is accessible for repairs.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. As an improved article of manufacture, a post consisting of longitudinally-flanged segments conn ectcd at diametrically-opposite sides by washers and bolts and thiinbles and bolts, substantially as and for the purpose specified.

2. As an improved article of manufacture, a post constructed of longitudinally-flanged segments, the opposed flanges of which segments are spaced by thimbles of varying length and Washers of Varying thickness, and bolts passed through the flanges, the Washers, and thirnbles, substantially as shown and described.

3. As an improved article of manufacture,

a post constructed of longitudinally-flanged segments, the opposed flanges of which segments are spaced by thimbles of varying length and Washers of varying thickness, bolts passed through the flanges, the Washers, and the thimbles, and gusset-plates secured horizontally at intervals between the flanges at diametrically-oppositc sides of the post, substantially as and for the purpose specified.
